I have been having troubles with Netflix with EVERY device in my home. All other internet sites work fine but not Netflix. Yet, I can get Netflix using cellular (so Netflix is up). I saw other posts on renewing DHCP lease and turning router firewall off but these did not help. I did a Tracert check and found all devices in my house were getting a one-hop to an Amazon.aws site where it ended.
I called tech support and they told me I had to upgrade my router for another $13 a month to allow Netflix...nope, that makes NO sense since every other site works. The tech actually encouraged me to switch to another ISP as a solution since I would not upgrade! Seriously? I ended the chat and will seriously explore that option based on that level of customer service.
I fixed the problem by deselecting auto-DNS in the router and I gave it a primary of Google (8.8.8.8) and secondary of OpenDNS (208.67.222.222). Boom - Netflix is back in action. In other words it appears that Verizon's DNS is blocking Netflix.
